Abstract: BACKGROUND The relationships between scan duration, signal-to-noise ratio (SNR) and sample size must be considered and understood to design optimal GABA-edited magnetic resonance spectroscopy (MRS) studies. NEW METHOD Simulations investigated the effects of signal averaging… read more here.

DOI: 10.1186/s40658-021-00380-9
Abstract: Background Time-of-flight (TOF) PET technology determines a reduction in the noise and improves the reconstructed image quality in low count acquisitions, such as in overweight patients, allowing a reduction of administered activity and/or imaging time.… read more here.

DOI: 10.3390/diagnostics12051277
Abstract: Background: Resting-state functional magnetic resonance imaging (rs-fMRI) can evaluate brain functional connectivity without requiring subjects to perform a specific task. This rs-fMRI is very useful in patients with cognitive decline or unable to respond to… read more here.
